Avoid overfilling fresh water

[rvshrinker]

We’re going on our first longish dry camp. 4 days/3 nights We are planning to fill our fresh water off city water before going.

I have a fresh water pressure regulator, and an inlet hose.

Tell me what to do so I don’t overfill or cause some problem.

It always amazes me, when I fill my 30 gallon fresh tank all the way. It drips a little out the fill cap and vent tube as I maneuver out of my driveway for our trip, as expected, and yet three hours of driving later, if I stop for gas, I still managed to leave a few drips. I would think after a 3 Hour Drive, all the water in the filler neck would have all been splashed out.

What ever you do don't walk away while you're filling the water tank. My brother in-law got sidetracked and forgot to turn the hose off. As a result the fresh water tank blew up and the floor raised inside his motorhome. That was an expensive mistake.

Fill it slow and easy though. The air must escape out the overflow tube which is a smaller diameter than the water inlet. Fill it too fast and the air will burp out the inlet and get you wet.

It sounds like the OP is planning to use the pressure fill, not gravity fill.

Doesn't matter, fill it till it runs out somewhere, the vent(s) need the bugs and road dirt flushed out anyway.

Do you KNOW that you fill the tank via the "city water" connection or are you assuming that ? Many have a separate "port" for filling the tank directly from a hose.

As has been said, overfilling should not be a real problem but some might slosh out the overflow the first few miles.

If you can SEE the actual tank, you might be able to see the water level in it too.

No biggie if you fill it right to the top.
It will run out via the overflow if you go around a corner and the water sloshes over.
